Cloud Bigtable: Node.js Client

release level npm version codecov

Cloud Bigtable Client Library for Node.js

A comprehensive list of changes in each version may be found in the CHANGELOG.

Read more about the client libraries for Cloud APIs, including the older Google APIs Client Libraries, in Client Libraries Explained.

Table of contents:

Quickstart

Before you begin

  1. Select or create a Cloud Platform project.
  2. Enable billing for your project.
  3. Enable the Cloud Bigtable API.
  4. Set up authentication with a service account so you can access the API from your local workstation.

Installing the client library

npm install @google-cloud/bigtable

Using the client library

// Imports the Google Cloud client library
const {Bigtable} = require('@google-cloud/bigtable');

const bigtable = new Bigtable();

async function quickstart() {
  // Connect to an existing instance:my-bigtable-instance
  const instance = bigtable.instance(INSTANCE_ID);

  // Connect to an existing table:my-table
  const table = instance.table(TABLE_ID);

  // Read a row from my-table using a row key
  const [singleRow] = await table.row('r1').get();

  // Print the row key and data (column value, labels, timestamp)
  const rowData = JSON.stringify(singleRow.data, null, 4);
  console.log(`Row key: ${singleRow.id}\nData: ${rowData}`);
}
quickstart();

Samples

Samples are in the samples/ directory. Each sample's README.md has instructions for running its sample.

Supported Node.js Versions

Our client libraries follow the Node.js release schedule. Libraries are compatible with all current active and maintenance versions of Node.js.

Client libraries targeting some end-of-life versions of Node.js are available, and can be installed via npm dist-tags. The dist-tags follow the naming convention legacy-(version).

Legacy Node.js versions are supported as a best effort:

  • Legacy versions will not be tested in continuous integration.
  • Some security patches may not be able to be backported.
  • Dependencies will not be kept up-to-date, and features will not be backported.

Legacy tags available

  • legacy-8: install client libraries from this dist-tag for versions compatible with Node.js 8.

Versioning

This library follows Semantic Versioning.

This library is considered to be General Availability (GA). This means it is stable; the code surface will not change in backwards-incompatible ways unless absolutely necessary (e.g. because of critical security issues) or with an extensive deprecation period. Issues and requests against GA libraries are addressed with the highest priority.
